Emergency response in cascading scenarios triggered by natural events

Ricci, Federica (author), Yang, M. (author), Reniers, G.L.L.M.E. (author), Cozzani, Valerio (author)

Emergency response is a procedural safety barrier of paramount importance for the mitigation of fire scenarios and the prevention of escalation. However, in Natech scenarios, emergency response may be affected by the natural event impacting the site. Indeed, when contrasting Natech accidents, emergency responders have to face both the natural...

Dynamic risk assessment of chemical process systems using the System-Theoretic accident model and process approach (STAMP) in combination with cascading failure propagation model (CFPM)

Sun, Hao (author), Wang, Haiqing (author), Yang, M. (author), Reniers, G.L.L.M.E. (author)

To maintain continuous production, chemical plant operators may ignore faults or handle faults online rather than shutting down process systems. However, interaction and interdependence links between components in a digitalized process system are substantial. Thus, faults will be propagated to downstream nodes, potentially leading to risk...

Uncertainties and their treatment in the quantitative risk assessment of domino effects: Classification and review

Xu, Y. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author), Yuan, S. (author), Chen, Chao (author)

Domino accidents are typical low-frequency and high-consequence events in chemical process industries. Applying quantitative risk assessment (QRA) in domino accident assessment is challenging due to the uncertainties in the escalation process. Meanwhile, the outcomes of QRA are subject to a certain degree of unreliability due to the...

A risk-based approach to inspection planning for pipelines considering the coupling effect of corrosion and dents

Huang, Y. (author), Qin, Guojin (author), Yang, M. (author)

RBI, referring to a risk-based approach to inspection planning, is an established pipeline integrity management method. Both corrosion and dents are the primary threats to pipeline integrity. However, they are often treated separately in RBI without considering their interactions. This coupling may lead to a synergic effect on integrity...

A Bayesian-network approach for assessing the probability of success of physical security attacks to offshore Oil&Gas facilities

Iaiani, Matteo (author), Tugnoli, Alessandro (author), Cozzani, Valerio (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)

Offshore Oil&Gas facilities are attractive targets of intentional malicious attacks (security attacks) that may trigger cascading events (e.g., the release and dispersion of hazardous material and/or energy, fires, explosions) with consequences on people, environment, and assets. The severity of these consequences is potentially similar to...
